Yes it's old, but they just went on sale today and a shipping date of the end of the year. So, these machines which will cost upwards of $9300, and are machines that could render the CGI in a James Cameron movie in a few minutes, are only shipping with FirePro video cards, specially tuned to Apple's specs (hence the D300, D500, and D700 names). No Tesla cards with CUDA, just FirePro with OpenCL...
